Introduce the x-icon custom element and migrate first-party WebUI and bundled plugin markup while retaining legacy Material icon compatibility. Defer icon-font readiness until the splash-installed document is parsed so Firefox does not leave icons transparent. Centralize chat message collapse handling, avoid false Show More controls on short user messages, and align grouped-message pagination styling. Update DOX and add regression coverage for the icon and collapse behavior.
List bundled slash commands in their own section and create same-name project or global overrides when users edit them.
Remove the Commands sidebar shortcut and redundant scope banner, then simplify command cards by dropping badges and argument hints while tightening description typography. Add regression coverage for built-in listing and override precedence.
Introduce the _commands plugin with command storage, picker UI, bundled canonical command pack, and legacy migration into the built-in namespace.
Polish the Web UI picker behavior, hide WebUI-only-inappropriate commands from the popover, make /models always open model configuration, and add regression coverage for command CRUD, plugin discovery, migration, canonical names, hidden commands, and picker flows.
